Protecting your business from cyber-attacks: Temperature monitoring that’s independent of fridge management systems

Kelsius provides independent temperature monitoring. It does not control the operation of refrigerators or freezers.

This distinction is key following the recent reports of cyber incidents affecting refrigeration systems across Europe.

Kelsius sensors independently monitor temperatures within refrigerated environments. The Kelsius system does not control the refrigeration unit, compressor, defrost cycles or other operational functions.

This separation is important.

If a refrigeration control system experiences a fault, malfunction or cybersecurity incident that results in a temperature deviation, Kelsius provides an independent monitoring layer designed to detect that deviation and alert designated personnel.

Cybersecurity and Data Protection

Kelsius applies established cybersecurity controls across its platform, including:

  • ISO 27001 compliance through its cloud hosting partner, AWS
  • Cyber Essentials certification
  • Encryption of data at rest and in transit
  • Multi-factor authentication, roles and permissions
  • Secure software development practices including threat modelling, code reviews, vulnerability management, incident resolution management and security testing

Data Resilience and Backup

Kelsius has multiple layers of data resilience built into the monitoring system.

  • If communication between an individual sensor and the Network Controller is interrupted, monitored data is retained locally by the sensor and transmitted once communication is restored. The Network Controller also incorporates local memory, providing another layer of protection against the loss of monitoring records.
  • The Network Controller has an integral back-up battery, allowing the monitoring system to continue operating during a power interruption. The system can also alert designated personnel should the Network Controller lose communication with the Kelsius portal.
  • Once transferred to the Kelsius cloud platform, data benefits from resilient storage, backup and redundancy, including self-healing data storage and automated crash recovery across multiple data centres.

This multi-layered approach provides resilience at the sensor, Network Controller and cloud platform levels, meaning that a temporary loss of network connectivity does not automatically result in the loss of temperature records.

Kelsius monitors your refrigeration equipment, it does not control it.

The key reassurance that Kelsius provides is that it operates independently of refrigeration control systems. Should refrigeration equipment experience a fault or disruption, Kelsius provides a separate layer of monitoring designed to identify any resulting temperature deviation and alert your team, allowing you to take appropriate action quickly and protect your products.

Lessons from France in Cybersecurity and Food Safety: Protecting the systems that protect your food

On the night of 11 to 12 October 2026, an overnight cyberattack affected refrigeration systems in hundreds of French supermarkets. Fresh and frozen products had to be discarded after temperatures rose. The incident has highlighted concerns about outdated firmware and equipment that no longer received security updates. As the incident continues to be investigated, the practical consequences included disrupted stores, significant amounts of food waste, and financial losses.

The incident raises questions for every food business using connected technology. How well are we protecting the systems we depend on to keep food safe?

A fridge can look perfectly normal from the outside while the food inside is becoming unsafe. In a connected food business, the cause could be a mechanical fault, a power failure or something less visible like a cyberattack on the system controlling refrigeration.

The digitalisation of food safety management

Managers of food businesses are responsible for a mix of refrigeration units, storage areas, deliveries, hygiene checks, records and regulatory responsibilities (as well as delivering service to customers and managing teams). Much of this work continues around the clock, even when the premises are closed and staff have gone home.

Connected equipment, digital records and temperature monitoring can improve visibility and reduce reliance on someone being physically present to spot a problem. For businesses operating across several locations, these tools can make essential information easier to access and act on.

However, connectivity can also create extra work and responsibilities. The UK’s National Cyber Security Centre warns that increasingly connected operational technology brings security risks alongside benefits such as remote monitoring and maintenance. A cyber incident affecting physical equipment can have consequences beyond the loss of data.

For food business managers, cybersecurity adds a layer of responsibility about operational continuity and food safety, alongside equipment maintenance and staff training.

The role of technology

The French incident provides businesses with a timely reminder to check the technology behind their refrigeration. A unit may keep food cold today while outdated software leaves its controls vulnerable to interference tomorrow.

Start by identifying your connected equipment, its software or firmware version and its support status. Firmware is the software embedded in equipment such as refrigeration controllers. Ask your supplier which systems still receive security updates, and which need an upgrade or replacement.

Make updates part of planned maintenance. Agree who tracks security notices, who installs updates and who checks that the equipment operates correctly afterwards. Work with qualified technicians to schedule and test changes without compromising refrigeration.

If a supplier no longer supports a controller, establish a replacement plan and ask your technical team how to reduce its exposure in the meantime. Do not assume that a functioning fridge has a secure control system.

Control who can access connected equipment

Remote access helps suppliers diagnose faults and maintain equipment, but businesses need to retain control over who can access their equipment.

Change default passwords, give each authorised user an individual account where supported, and restrict permissions to the tasks they need to perform. Protect remote access with multi-factor authentication and remove access when a staff member or contractor no longer needs it.

Ask your IT provider to separate refrigeration controls from guest Wi-Fi and other networks appropriately. Suppliers should use a secure, controlled route for remote support.

These steps reflect National Cyber Security Centre guidance on protecting operational technology. They reduce opportunities for unauthorised access and help limit the consequences if another part of the business’s network suffers an attack.

Choose suppliers who take security seriously

Reliable technology needs reliable support throughout its working life. Ask suppliers to explain their security arrangements in clear terms before you purchase a system, and review those arrangements regularly.

How long will they provide security updates? How quickly will they notify you about a vulnerability or service disruption? Who handles urgent issues outside office hours? What happens when equipment reaches the end of its supported life?

Request clear responsibilities and contact details. Make sure you have a nominated person responsible for coordinating security updates.

Automated alerts allow for faster reactions

Prevention reduces risk. Automated monitoring helps businesses act when a problem still occurs, whether a cyberattack, equipment fault or power failure causes it.

Configure your monitoring system to send notifications as soon as it detects a condition that meets the agreed alert criteria. Those notifications need to reach the responsible people at any hour, including overnight, at weekends and during holidays.

Use suitable channels, such as push notifications, email or voice calls, according to the system’s capabilities and the urgency of the issue.

Set alert thresholds around your food safety procedures. Check how frequently the system measures temperatures and how quickly it delivers notifications. An immediate notification after detection still depends on those settings and a working communication route.

Where supported, enable alerts for missing readings, lost connections and device faults too. A monitoring system that stops reporting needs attention, even if it has not recorded a temperature breach.

Make sure alerts reach someone who can act

An alert at 2am only helps if someone receives it and takes responsibility.

Create an out-of-hours contact rota, assign a backup and set an escalation process for unacknowledged alerts. Keep phone numbers and app settings current. Test the notification route and response arrangements regularly, including outside normal working hours.

Give staff a clear action plan. Identify who can access the premises, contact an engineer and authorise stock movement. Arrange alternative refrigerated storage in advance and confirm that it offers suitable conditions and enough capacity.

Early notification may give a team time to move products before conditions deteriorate further. If stock has already become unsafe, it can still help managers restrict sales, arrange disposal and bring in cleaning teams before customers arrive.

Reducing the impact of fridge failures

Temperature monitoring detects changes in storage conditions; it does not necessarily identify their cause. Businesses still need cybersecurity controls to protect equipment and investigate suspicious activity.

For businesses holding substantial chilled or frozen stock, an incident could put tens of thousands of euro worth of food at risk. Disposal, repairs, cleaning and interrupted trading can add to the cost.

The lesson from France highlights the importance of maintaining supported technology, controlling access and establishing clear communications with suppliers. Make sure that your food safety plan continues after closing time, and not just during business hours.

For advice on automated temperature monitoring and 24-hour, real-time temperature alerts, contact Kelsius.

Davy Byrnes simplifies food safety compliance, saves staff time and makes safety checks easier

Davy Byrnes is one of Dublin’s most recognised pubs, known for its literary heritage, distinctive character and reputation for quality food and hospitality. With a busy kitchen, multiple staff members and several cold-storage units, its food safety procedures must be efficient, reliable and easy to follow.

 

 

Before introducing Kelsius FoodCheck 2.0, the team relied on paper records to document food temperatures and daily HACCP checks. This required considerable staff time, created additional administration and made it more difficult for management to review completed checks.

With the implementation of FoodCheck 2.0, sensors now automatically monitor temperatures across multiple refrigeration and freezer units. Kitchen staff use connected digital probes to record cooked-food temperatures quickly during normal service.

The system has reduced paperwork and repetitive manual checks, while giving staff more time to focus on core kitchen duties. Straightforward digital processes are easy to learn and use across different shifts and experience levels.

Temperature records, completed checks and reports are stored digitally in one place. This gives Davy Byrnes management clearer oversight of food safety activity and allows reliable records to be accessed quickly for audits, internal reviews and Environmental Health Officer (EHO) inspections.

By improving consistency, accountability and access to information, FoodCheck 2.0 gives Davy Byrnes greater confidence that essential food safety checks are completed and that reliable evidence is available when required.

Hours saved daily, instant traceability – just some of the benefits The Beaumont Mayfair enjoys using Kelsius

Operating at five-star standards leaves no room for compromise, especially when it comes to food safety. At The Beaumont Mayfair, a luxury London hotel with multiple kitchens, dining areas, and service environments, maintaining compliance across departments was becoming increasingly complex.

The Challenge

Before introducing Kelsius FoodCheck 2.0, the team relied heavily on paper-based processes. This created unnecessary administration, limited real-time visibility, and introduced risk around record accuracy, particularly during busy service periods. In an environment where rapid access to accurate data is critical, this approach left gaps in traceability and audit readiness.

 

 

Following implementation of the Kelsius system, the impact was immediate.

Digital workflows replaced manual checks, allowing kitchen teams to complete tasks quickly and consistently using probes and tablets. Management gained instant oversight across more than 20 refrigeration units, with automated monitoring and alerts helping prevent stock loss and reduce risk. Reporting, once time-consuming, is now accessible in seconds, supporting daily operations and audit preparation.

Hours saved daily, instant traceability

The hotel estimates a time saving of two to three hours per day, driven by faster checks, automated monitoring, and streamlined reporting. Beyond efficiency, the shift to tamper-proof digital records has strengthened due diligence and eliminated the risk of falsified entries.

Crucially, the system provides instant traceability across all operations, from goods-in to cooking compliance, while remaining flexible enough to match the hotel’s HACCP requirements.

Today, Kelsius is embedded across the Beaumont’s kitchens, pastry, private dining, and bar operations. The result is a more controlled, consistent, and confident approach to food safety, one that meets the expectations of a five-star environment while freeing up valuable time for staff to focus on service.
